Hero of Elucia by I. T. Lucas

Kailin’s gift made her a hero, but now it’s making her a target.

To reach the bonding ceremony, she must survive not only assassins but also the immense physical and mental strain of her prophetic dreams. Her nightmares whisper of sinister forces, betrayals yet to come, and mortal danger to those she loves.
Alar left his father’s royal court to forge his own destiny as a dragon rider, but what he found in Elucia is more than he could have ever imagined—love, purpose, and a life of his own design. Yet crowns cast long shadows, and when a letter arrives from his mother, Alar is faced with an impossible choice.
The prophecy speaks of seven who will save Aurorys. Six have been found, but one remains a mystery—and time is running out.
